VEHICLE-WHEEL TIRE.

Application filed July 10, 1909,.Seria1 No. 508,868.

To all whom it may concern:

Be it known that ll, MICHAEL B, CARMODY, a citizen of the United States,and a resident of Columbus, in the county of Franklin and State of Ohio,have invented a new and improved Vehicle-Wheel Tire, of which thefollowing is a full, clear, and exact descriptie-n.

This invention relates to a class of vehicle tires having a tubularexpansible body, that is attachable to the rim of a vehicle wheel, andinterior elastic distending means, which afiord support to the body.

The purpose of my invention is to provide a vehicle wheel tire of theclass indicated,

which embodies novel details, that are simple, durable, afiord interiorventilation and elastic support to the body of the tire, and whichpermit a quick and convenient detachment of the exterior of the body ofthe tire from the wheel rim, as Well as the removal of said noveldetails from the tire body if occasion requires.

The invention consists in the novel construction and combination ofarts, as is hereinafter described and defined in the appended claims. 7

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views, and in which- Figure l is a sideview of a vehicle wheel and of the improved tire mounted thereon, aportion of the tubulate body of said tire be- -1ng removed, exposingnovel details; Fig. 2

is an enlarged transverse sectional view substantially on the line 2-2in Fig. 1; and Fig. 8 is a transverse sectional view of the improvement,showing an additional feature of the invention. y

In the drawings, 5 indicates a vehicle wheel of a type which receives anelastic tire, and 6, a wheel felly that has a true cylindricalperiphery, Whcrcon is secured a clencher rim 7 said rim at each sidethereof havin a semi-circular clamping member 8, of we -knownconstruction.

The tire proper consists of an open tubu l'ated ring 9 formed ofsuitable material having a proper degree of elasticity. Upon the outerside of the tire body 9, at the edges thereof that define the slot-likeopening therein, a semi-circular rib is formed on each edge thatprojects outwardly, as shown at a, a, 1n Figspl and 3. Opposite the ribsSpecification of Letters Patent are each Patented May 3d, 1911.

I Renewed ()ctober 28, 1910. Serial No. 589,592.

a, a, on the inner side of the tire body 9, two similar angular ribs 6,b are respectively formed. The elastic core that fills the tire body 9is in two half sections 10, 11, that in continuous ring form. One halfsection 10 for the core is formed with an annular recess 0, in the sidethat has contact with the half section 11, said recess having a fiatbottom, and two 0 positely inclined sides 0 c. The flaring si es 0 c ofthe recess c are of an equal height, and at their upper ed es 0 0 meettwo outwardly and downwardly inclined sides-0 c on the section 10, wlnchsides 0 c extend respectively to the u per and lower surface of the saidhalf section 10; and it will be seen that the junction of each pair ofinclined sides 0 0 produces an angular transversely disposed projection,the apex of which is at 0 The As shown in Figs. 2 and 3, the inclinedsurface 6' of each angular rib 7) on the inner side of the tire body 9which 1s farthest from the upper surface of each half section 10,

11, slopes downward and toward the con-' cave inner surface of said tirebody, into which said sloping surfaces merge.

In the outer face of each half section 10, 11, an angular recess isformed that receives a corresponding angular rib b whcnihc twoart corebody is fully inserted wlthm the hollow tire body 9.

Near the center of each core section 10, 11, an annular continuous airchamber 12 is formed therein, said chambers being of an equal size andoval in cross section, but on their sides that are nearest to each otherbeing rendered obtuse angular, thus reducing the thickness of the walls0, that separate the core sections at their centers. In tires that aresubjected to great load strain, the chambers 12, may each be filledloosely by the insertion thereinto of a sectional filling ring 13, saidrings being elastic and transversely perforated at intervals as shown inFig. 3.

A plurality of transverse air passages g are formed inthe core halfsections 10, 11, that register with each other in pairs, and an airpassage is formed in the dividing walls between the core sections, whichconnects the chambers 12, two of the air passages 9 extending laterallyfrom said chambers'. At suitable points, preferably equally distant fromeach other, similar air ducts h are formed in the core section 10, saidducts extending from the air chamber 12 through the wall of said coresection that is adjacent to the clencher rim 7. Opposite each air duct han air-eontrolling'short tube 2' is inserted through and secured in thewheelfelly 6 and clencher rim 7 the passages in each of said tubes beingcontrolled by a valve 11, whereby the inflow and escape of air into andfrom the interior of the core rings 10, 11 may he graduated b anadjustment of 4 said valves. A circum ercntial groove n is formed in theinner surface of the tire section 10, at a oint which adapts the airducts It and tubes 2 to communicate therewith, and thus facilitate afree circulation of air in the sections 10 and 11.

In the inner surface of the tubulated tire body 9, at suitable points,inwardly-projecting short studs m are formed, that are seated incorrespondingly-shaped sockets in the core sections 10, 11, theinterlocking engagement of the studs and sockets preventing the vcoresections from creeping within the tire ring 9.

The angular formations on the inner sides of the core rings 1.0, 11,prevent one section from shifting on the other one, and the engagementof the angular ribs 1) Within the V-shaped recesses in the core halfsections 10, 11 serves to lock the tire body 9 upon the core halfsections while the convcxed ribs a, a are interlocked with the clenchingrim 7 It will be noted that the tree circulation of air throughout theinterior of the tire body, prevents excessive heat therein which causesdecay-and loss of roper'elasticity.

When it is essential t at the tire and itsv core be charged withconfined air, that will reduce the degree of elasticity, the valves 2"may be closed, which will retain the air in the tire, and adapt it tosustain a greater load, without flattening the engaged peripheralsurface of the same.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent 1.
